Module description
Without the careful measurement of hydrostatic forces, structures like the Hoover Dam or the Tamar Bridge could not have been built. This examination of static fluid, which underpins much of civil engineering and mechanical engineering design, is just one of the key areas you will explore on this module.
On this module, you will encounter fluid flow equations and principles, tension compression and learn how to calculate forces from stagnant fluids. In a hands-on laboratory session, you will measure the force from a water jet, heating different surfaces, and then illustrate your results in diagrams.
On completing this module, you will be familiar with the basics of fluid flow principles and conservation laws by which practically all fluid flow problems are solved, you will have an excellent foundation in critical measurement techniques and be proficient in using a hydraulic bench, in this case, equipped with a pump and simple system to measure flow rate.
Prerequisite module: INT1108
Module aims - intentions of the module
The aim of this module is to introduce you to fundamental concepts of solid mechanics and fluid mechanics, separated into two sections (half a term each). For solid mechanics this includes stress/ strain relationships, axial members, rods and beams. For fluid mechanics this covers fluid properties, continuity and energy equations, momentum, and engineering concepts like buoyancy and hydrostatics.

Re-assessment notes
Deferral – if you miss an assessment for reasons judged legitimate by the Mitigation Committee, the applicable assessment will normally be deferred. See ‘Details of reassessment’ for the form that assessment usually takes. When deferral occurs there is ordinarily no change to the overall weighting of that assessment.
Referral – if you have failed the module overall (i.e. a final overall module mark of less than 40%) you will be required to take a re-sit exam. Only your performance in this exam will count towards your final module grade. A grade of 40% will be awarded if the examination is passed.
